Python programming using def function
Give the user a math quiz where they have
to subtract 2-digit integers. Present them
like this: 67 - 55.
Each time, tell the user whether they are
correct or incorrect. Continue presenting
problems to them until they enter a zero to
quit. At the end print the number right,
the number wrong, and the percent right.
Answers
Explanation:
For this program we'll need to know a couple concepts which are: while loops, user input, variables, converting strings to integers, and basic arithmetic operators, if statements, and the random module.
So let's first just declare the basic function, we can call this "main", or something a bit more descriptive, but for now I'll name it "main".
def main():
# code will go here
main()
so now from here, we want to initialize some variables. We need to somehow keep track of how many they get correct and how many they've answered.
These two numbers may be the same, but at times they will be different from each other, so we'll need two variables. Let's just call the variable tracking how much have been answered as "answered" and the variable tracking how much are correct as "correct".
These two will initially be zero, since the user hasn't answered any questions or gotten any correct. So now we have the following code
def main():
correct = 0
answered = 0
main()
Now let's use a while loop, which we break out of, once the user inputs zero. This may be a bit tricky if we use a condition since we'll have to ask for input before, so let's just use a while True loop, and then use an if statement to break out of it at the end of the loop.
Now we want to generate two numbers so we can use the random module. To access the functions from the random module you use the import statement which will look like this "import random". Now that you have access to these functions, we can use the randint function which generates random numbers between the two parameters you give it (including those end points). It says two digits, so let's use the endpoints 10 and 98, and I'll explain later why I'm limiting it to 98 and not 99.
The reason we want to limit it to 98 and not 99, is because it's possible for the two randomly generated numbers to be equal to each other, so the answer would be zero. This is a problem because the zero is used to quit the program. So what we can do in this case, is add one to one of the numbers, so they're no longer equal, but if they're equal to 99, then now we have a three digit number.
Now onto the user input for simplicitly, let's assume they enter valid input, all we have to do is store that input in a variable and convert it into an integer. We can immediately convert the input into an integer by surrounding the input by the int to convert it.
we of course want to display them the equation, and we can either do this through string concatenation or f-strings, but f-strings are a bit more easier to read.
So let's code this up:
import random
def main():
correct = 0
answered = 0
while True:
num1 = random.randint(10, 98)
num2 = random.randint(10, 98)
if num1 == num2:
num2 += 1
userInput = int(input(f"{num1} - {num2}"))
main()
from here we first need to check if they entered zero and if so, break out of the loop. If they didn't enter zero, check if the userInput is equal to the actual answer and if it is, then add one to correct and finally add one to answered regardless of whether their answer is correct or not.
Outside the loop to display how much they got correct we can use an f-string just like we did previously. Since sometimes we'll get a non-terminating decimal, we can use the round function so it rounds to the nearest hundreth.
So let's code this up:
import random
def main():
correct = 0
answered = 0
while True:
num1 = random.randint(10, 98)
num2 = random.randint(10, 98)
if num1 == num2: # the answer would be zero
num2 += 1 # makes sure the answer isn't zero
userInput = int(input(f"{num1} - {num2}"))
if userInput == 0: # first check if they want to stop
break
if userInput == (num1 - num2):
correct += 1
answered += 1
print(f"Correct: {correct}\nIncorrect: {answered - correct}\nPercent: {round(correct/answered, 2)}")
main()
and that should pretty much be it. The last line is just some formatting so it looks a bit better when displaying.

Ask the user to think of a number between zero and one hundred. Your goal is to guess the number in as few guesses as possible. The user will inform you if you guessed too high, low or correct. Start by always guessing the middle number 50. If the user informs you it’s too low, then try 75. If 50 was too high, then try 25. Always guess the middle of the range of numbers left. In doing so, the range of numbers will be cut in half after each guess. If done correctly, no more than 7 guesses are needed. Print out “you cheated” if you reach 7 guesses and are still wrong.

Explanation:
Encryption encrypts data so that it can not be understood if/when it is intercepted by a third party between the sender and the recipient.
For example, if you're encrypting via the keyword vanilla, and then sending an email to Bob saying "Hi Bob", it would get encrypted as something like Vjh D5xx. The recipient would then use the keyword vanilla to decrypt this message so they can read it as Hi Bob. Anyone who intercepts this wouldn't have the keyword, and would just see incoherent letters, numbers, and symbols that they couldn't make heads or tails of.
Secure websites use technology that scrambles the information you send. This is known as, Encryption. So, the correct option is B.
Given that,
Secure websites use technology that scrambles the information you send.
Since, Secure websites use encryption technology to scramble the information you send, ensuring that it remains secure and protected during transmission.

b) the program assigns the immutable variable “arr” to an array of intagers. It then iterates over the items of the array starting at index zero. The current value is declared as “item”. It will then print item cast as a string to the console.
c) this program is poorly designed due to the use of “SetTimeout”. During each iteration, the program will await item milliseconds before printing the item to the console. This affects the speed of the program due to thread sleeps every iteration
Write an SQL statement to display for every restaurant the name of the restaurant (where the name of the restaurant consists of more than 10 characters) and for every category of menu item its description (catdesc). Furthermore, display the average; cheapest or lowest; and highest or most expensive price of all menu items in that category at that restaurant. Use single row functions to format all the prices. The average price must be padded; the cheapest price must be rounded; but the highest price must not be rounded. Display only those menu items of which the average item price is more than R40. Sort your results according to the restaurant names and for every restaurant from the most expensive average menu item to the cheapest average menu item. Display your results exactly as listed below.

A computer network is a collection of computers that share resources that are located on or provided by network nodes. To interact with one another, the computers employ standard communication protocols across digital linkages.
The Internet of Things refers to physical items equipped with sensors, processing power, software, and other technologies that communicate and share information with other devices and processes over the Internet or other network infrastructure.
Sensors, microprocessors, storage systems, controls, programming, and embedded system software with enhanced user interface make up a smart object.
A microcontroller is a small integrated circuit that controls a single function in an embedded system. On a single chip, a typical microcontroller has a CPU, memory, and input/output (I/O) peripherals.
All the above are part of computer architecture.
What is computer architecture?Computer architecture is a collection of principles and procedures used in computer engineering to explain the functioning, structure, and deployment of computer systems. A system's architecture refers to its structure in terms of individually stated components and their interrelationships.
The hardware, system software, and user layers comprise computer architecture.

Can someone help me out with a code. Code's in python write a function that returns the longest common prefix of two strings. For example, the longest
common prefix of distance and disinfection is dis. The header of the method is:
def prefix(s1, s2)
If the two strings have no common prefix, the method returns an empty string.
Write a main function that prompts the user to enter two strings and displays their common
prefix.
here's what I have currently but its not working.
def longestCommonPrefix(self, arr):
arr.sort(reverse = False)
print(arr)
n= len(arr)
str1 = arr[0]
str2 = arr[n-1]
n1 = len(str1)
n2 = len(str2)
result = ""
j = 0
i = 0
while(i <= n1 - 1 and j <= n2 - 1):
if (str1[i] != str2[j]):
break
result += (str1[i])
i += 1
j += 1
return (result)
